DETAILED DESCRIPTION

[0010] The disclosure is illustrated by way of example and not by way of
limitation in the figures of the accompanying drawings in which like
references indicate similar elements. It should be noted that references
to "an" or "one" embodiment in this disclosure are not necessarily to the
same embodiment, and such references mean "at least one."

[0011] FIGS. 1-3 illustrate an embodiment of a mounting apparatus for
mounting a number of mounting brackets 21 and expansion cards 22 to an
enclosure 10. The mounting apparatus includes a sliding member 30, a
resisting member 50, and a pushing member 60.

[0012] A number of extension slots 11 is defined in the enclosure 10. A
number of supporting brackets 12 bound the number of extension slots 11.
Two pivoting brackets 13 extend substantially perpendicularly from an
inner side of the enclosure 10 above the number of supporting brackets
12. Each of the two pivoting brackets 13 defines a pivoting hole 130
therein. Two receiving slots 14 and two mounting holes 15 are defined in
the enclosure 10 above the number of supporting brackets 12. In at least
one embodiment, the two mounting holes 15 are located between the two
receiving slots 14.

[0013] Each of the two mounting holes 15 includes an inserting portion 151
and a restriction portion 152 communicating with the inserting portion
151. A mounting portion 17 extends from an outer side of the enclosure
10. In at least one embodiment, the mounting portion 17 is a
substantially hollow cylinder. The mounting portion 17 is located between
the two mounting holes 15. Two locking holes 170 are defined in two sides
of the mounting portion 17. An abutting bracket 16 extends from the inner
side of the enclosure 10. In at least one embodiment, the abutting
bracket 16 is located at an outer side of one of the two receiving slots
14.

[0014] In the embodiment, each mounting bracket 21 is substantially
L-shaped. Each mounting bracket 21 includes a body 212 and a flange
portion 211 extending substantially perpendicularly from a top end of the
body 212.

[0015] The resisting member 50 includes a substantially rectangular
resisting bracket 51. Two guiding brackets 52 and two rotating axles 53
extend from two sides of the resisting bracket 51. Each of the two
guiding brackets 52 includes a stopping portion 521 connected to the
resisting bracket 51, and a locating portion 522 extending from the
stopping portion 521. In at least one embodiment, the resisting bracket
51 is substantially arc-shaped. A width of the stopping portion 521 is
greater than a width of the locating portion 522.

[0016] The sliding member 30 includes a substantially rectangular sliding
bracket 31. Two fixing members 34 are located on the sliding member 30
and correspond to the two mounting holes 15. Each of the two fixing
members 34 includes a head portion 341 and a pole portion 342. The pole
portion 342 is connected to the sliding bracket 31. A fixing hole 35 is
defined in the sliding bracket 31 and corresponds to the mounting portion
17. A pressing portion 37 protrudes from an inner side of the sliding
bracket 31 and partially covers the fixing hole 35. A fixing bracket 33
extends substantially perpendicularly from one end of the sliding bracket
31. A restriction slot 36 is defined in a bottom edge of the sliding
bracket 31.

[0017] In at least one embodiment, a size of the head portion 341 is less
than a size of the inserting portion 151, and greater than a size of the
restriction portion 152. A size of the pole portion 342 is less than the
size of the restriction portion 152. The pressing portion 37 is
substantially arc-shaped. The fixing hole 35 is located between the two
fixing members 34. The restriction slot 36 is adjacent to the fixing
bracket 33.

[0018] The mounting apparatus further includes a first elastic member 41
and a second elastic member 42. In at least one embodiment, the first
elastic member 41 and the second elastic member 42 are springs.

[0019] The pushing member 60 includes an operation portion 64 and a
connection portion 62 connected to the operation portion 64. A
substantially cone-shaped driving portion 61 extends from a distal end of
the connection portion 62. Two locking portions 63 are located on the
pushing member 60 and correspond to the two locking holes 170. In at
least one embodiment, a diameter of the operation portion 64 is greater
than a diameter of the mounting portion 17, and a diameter of the
connection portion 62 is less than the diameter of the mounting portion
17.

[0020] FIGS. 3-6 illustrate that, in assembly, the head portions 341 of
the fixing member 34 pass through the corresponding inserting portions
151. The pole portions 342 are received in the corresponding inserting
portions 151. A first terminal of the first elastic member 41 is mounted
to the fixing bracket 33. A second terminal of the first elastic member
41 resists against the abutting bracket 16.

[0021] A distance from the abutting bracket 16 to the fixing bracket 33 is
less than a relaxed length of the first elastic member 41. Thus, the
first elastic member 41 pushes the sliding member 30. The sliding member
30 moves along a first direction on the enclosure 10, thereby causing the
pole portions 342 to slide along the restriction portions 152 of the
mounting holes 15, and causing the restriction slot 36 of the sliding
bracket 31 to misalign with the receiving slot 14 of the enclosure 10.
Thus, the sliding brackets 31 cover the upper portions of the
corresponding receiving slots 14.

[0022] The two rotating axles 53 of the resisting member 50 are pivotably
received in the pivoting holes 130 of the enclosure 10. The guiding
brackets 52 of the resisting member 50 are aligned to the corresponding
receiving slots 14. The locating portions 522 pass through a lower
portion of the corresponding receiving slots 14. The sliding bracket 31
prevents the stopping portions 521 from passing through the corresponding
receiving slots 14.

[0023] The second elastic member 42 is sleeved on the connection portion
62 of the pushing member 60. The assembled connection portion 62 and the
second elastic member 42 are received in the mounting portion 17. The
operation portion 64 is pressed to elastically deform the locking
portions 63, thereby latching the locking portions 63 in the
corresponding locking holes 170. The pushing member 60 is mounted to the
mounting portion 17.

[0024] A first terminal of the second elastic member 42 resists against
the enclosure 10 in the mounting portion 17. A second terminal of the
second elastic member 42 resists against the operation portion 64. The
second elastic member 42 pushes the locking portions 63. The locking
portions 63 are latched in the corresponding locking holes 170. The
driving portion 61 is misaligned with the pressing portion 37.

[0025] In use, the operation portion 64 is pressed toward the enclosure
10, thereby deforming the second elastic member 42. The locking portions
63 slide into the corresponding locking holes 170. The driving portion 61
passes through the fixing hole 35 and resists against the pressing
portion 37. The driving portion 61 pushes the sliding member 30. The
sliding member 30 moves along a second direction opposite to the first
direction. Thus, the restriction slot 36 is aligned with the
corresponding receiving slot 14.

[0026] The resisting member 50 is rotated to pass the stopping portions
521 through the corresponding receiving slots 14. The operation portion
64 is released, and the second elastic member 42 is restored to latch the
locking portions 63 in the corresponding locking holes 170. The stopping
portions 521 prevent the sliding member 30 from moving back along the
first direction. The mounting brackets 21 and the expansion cards 22 are
mounted in the extension slots 11. The flange portions 211 of the
mounting brackets 21 contact the corresponding supporting brackets 12.

[0027] The resisting member 50 is rotated to move the stopping portions
521 out of the receiving slots 14. The first elastic member 41 pushes the
sliding member 30. The sliding member 30 moves back along the first
direction, causing the restriction slot 36 to misalign with the
corresponding receiving slot 14. The sliding bracket 31 prevents the
stopping portions 521 from passing through the receiving slots 14. The
flange portion 211 is secured between the resisting bracket 51 and the
supporting brackets 12.

[0028] In disassembly, the operation portion 64 is pressed to align the
restriction slot 36 with the corresponding receiving slot 14. The
resisting member 50 is rotated to pass the stopping portions 521 through
the receiving slots 14. Thus, the mounting brackets 21 and the expansion
cards 22 can be detached from the corresponding supporting brackets 12.

[0029] Even though numerous characteristics and advantages of the present
disclosure have been set forth in the foregoing description, together
with details of the structure and function of the disclosure, the
disclosure is illustrative only, and changes may be made in detail,
including in the matters of shape, size, and the arrangement of parts
within the principles of the disclosure to the full extent indicated by
the broad general meaning of the terms in which the appended claims are
expressed.
